I ran a SPARQL query that selects items that are instances of "geological formation" (wd:Q736917) and that are located in the United States of America (wd:Q30). Location in the USA is detected via country (P17), administrative territorial entity (P131 -> P17), or location (P276 -> P17). For each formation I counted distinct items that have that formation as their main subject (P921). The query returns the formation IRI, its English label (if available), and the count, ordered by count descending and then label ascending. Example top results include Green River Formation (wd:Q741367) with count 193, Marcellus Formation (wd:Q1554536) with count 116, and Phosphoria Formation (wd:Q7187546) with count 82. The full query is provided and was executed against the Wikidata endpoint.

What are the formations in the United States of America, along with their labels, and the number of items that have each formation as their main subject? Please order the results by the count in descending order, followed by the item label.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] What are the formations in the United States of America, along with their labels, and the number of items that have each formation as their main subject? Please order the results by the count in descending order, followed by the item label.

[Assistant] Step 1: I'll search for the Wikidata item corresponding to "geological formation" to identify the entity to use (e.g., instance of geological formation). I'll run a search for that phrase.

10. Ackerman Formation in Alabama: GEOLOGICAL NOTES (wd:Q67215940): instance of scholarly article

[Assistant] I will verify the property for "main subject" in Wikidata (expected P921). I'll search for the property.

[Tool]
Top 10 property alternatives:
1. main subject, also known as main topic, primary subject, primary keyword, plot keyword, of (wd:P921 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): primary topic of a work, subproperty of depicts

[Assistant] Now I'll craft a SPARQL query: Find items where wdt:P921 (main subject) is a geological formation (wd:Q736917) and that geological formation has country 'United States of America' (wdt:P17 wd:Q30). But formations are typically "located in" within country using P17? Need to check property for country (P17). Also formation items might have "country" or "located in the administrative territorial entity" (P131) or "located in present-day country" (P17 or P27?). Let's inspect usage on a sample formation. I'll search for items that are instance of geological formation and have country P17 USA.

[Assistant] Next I will run a SPARQL query that finds items that are instances of geological formation (wd:Q736917) and are located in the United States of America either directly via P17 or via P131/P17 or via P276/P17. For each formation I count distinct items that have that formation as their main subject (P921). I will include the formation IRI and its English rdfs:label (if available). Ordering will be by the count descending, then by the formation label ascending. Now I'll execute that query.

[Tool]
Got 3,268 rows and 3 columns, showing the first 5 and last 5 rows below:

[Assistant] The query returned results. Next, per the instructions I must explain my thought process before and after each function call — I have been doing that. Now I'll prepare the final SPARQL query (ensuring it returns identifiers and labels optionally) and produce the answer text describing the query and summarizing the results. I must also ensure I execute the final SPARQL query before answering—I've already executed one; I'll use it as final. I'll now call the answer function with the final query and a short summary.

5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[Assistant] Now I'll execute a refined final SPARQL query that finds items in Norway that are instances (or instances of subclasses) of cemetery (Q39614) or churchyard (Q2749813) and that have either CWGC burial ground ID (P1920) or Foreign war churchyards in Norway ID (P8387). The query will return the item IRIs, English label (if available), the two IDs, coordinates, and image. I'll run it to verify results.

I searched Wikidata for the items "video game genre" (wd:Q659563), "electronic game" (wd:Q2249149), and the OLAC video game genre vocabulary ID property (wdt:P6352). I built a SPARQL query that returns distinct items that are either: instances of video game genre (P31 = Q659563), or subclasses (transitively) of video game genre or electronic game (P279*), and for each item returns its IRI, English label (if available), its OLAC ID (P6352) if present, and any direct subclasses (with English labels). The provided SPARQL query can be executed against the Wikidata endpoint to get the full list. Note: including subclasses of electronic game (Q2249149) will include many items that are not strictly "genres" (e.g., individual games or hardware) because the class is broad; if you want only genre-like subclasses, we can refine the query to restrict to items that are also instances of video game genre or that have other genre-like properties.

Which distinct items are instances of video game genres, or subclasses of either video game genres or electronic games? Please return the genre, the OLAC video game genre vocabulary ID (if available), and any subclasses (if available).

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Which distinct items are instances of video game genres, or subclasses of either video game genres or electronic games? Please return the genre, the OLAC video game genre vocabulary ID (if available), and any subclasses (if available).

[Assistant] I will first find the Wikidata items for "video game genre" and "electronic game", then find the property that corresponds to the OLAC video game genre vocabulary ID. I'll run searches and explain results, then build queries to list items that are instances of video game genres or subclasses of either video game genres or electronic games, returning the genre item, its OLAC ID (if any), and any subclasses. I'll run intermediate queries to verify. Now I'll search for the "video game genre" and "electronic game" items.

[Assistant] Now I'll run a SPARQL query that finds all items that are either instances of video game genre (wd:Q659563), or subclasses (transitively) of video game genre or electronic game (wd:Q2249149). For each genre I will return the item's IRI, its OLAC video game genre vocabulary ID (wdt:P6352) if present, and any direct subclasses (wdt:P279) of that genre, plus English labels for readability. I'll execute the query to verify results.

SPARQL execution failed:

[Assistant] The query timed out. I'll try a more incremental approach: first retrieve items that are instances of video game genre (wdt:P31 wd:Q659563) and get their OLAC IDs. Then separately get items that are subclasses (wdt:P279*) of video game genre or electronic game, and combine. I'll start with instances of video game genre.

[Assistant] We have 456 instances of video game genre. Next, I'll query items that are subclasses (transitive) of video game genre (Q659563) or electronic game (Q2249149), getting their OLAC IDs. This may overlap with the instances, but we'll use DISTINCT later. I'll run a query for subclasses of either Q659563 or Q2249149 using wdt:P279* and get labels and OLAC IDs.

This subclasses query returned many items including individual games or hardware, which is too broad because electronic game (Q2249149) includes individual electronic games and hardware as subclasses. The user asked: "Which distinct items are instances of video game genres, or subclasses of either video game genres or electronic games? Please return the genre, the OLAC video game genre vocabulary ID (if available), and any subclasses (if available)."

Interpreting: we should return items that are either:
- instances of video game genre (P31 = Q659563), OR
- subclasses (P279) of video game genre (Q659563) OR
- subclasses (P279) of electronic game (Q2249149)

But we should filter to items that are "genres" — i.e., likely instances of video game genre or subclasses of video game genre. Including subclasses of electronic game will bring many non-genre items. Perhaps the user really wants the union: items that either are instances of video game genres, or are subclasses of either video game genres or electronic games. That's what I implemented; but we need to present "genre" (item), its OLAC ID, and any subclasses (if available). We should avoid listing non-genre items (like consoles). Maybe constrain subclasses to those that are subclasses of the genre items, not subclasses of electronic game broadly.

Reread: "instances of video game genres, or subclasses of either video game genres or electronic games" The phrase "either video game genres or electronic games" suggests subclasses of (video game genres) or subclasses of (electronic games). So include subclasses of electronic games too.

But when including subclasses of electronic games, we might include many irrelevant items. Still, follow user's instruction.

We must ensure final query returns distinct items, their OLAC ID (P6352), and any subclasses (P279). So for each genre item (the item in the union), we should also list its subclass items (direct subclasses). Also include labels (optional in OPTIONAL). The query might be large; but we need to run it and ensure it finishes.

Let's craft a final SPARQL that picks ?genre where:
- ?genre wdt:P31 wd:Q659563
  OR ?genre wdt:P279+ wd:Q659563 (subclass of genre)
  OR ?genre wdt:P279+ wd:Q2249149 (subclass of electronic game)
Then OPTIONAL ?genre wdt:P6352 ?olacID.
OPTIONAL ?subclass wdt:P279 ?genre.
Get labels for genre and subclass in English.

Use DISTINCT. Order by genreLabel, subclassLabel.

I'll run the final query. Include rdfs:label. Ensure property wdt:P279* or + for transitive: use wdt:P279* maybe allowed. Use wdt:P279+ to require at least one step. But we also have instances; keep combining with UNION. Use parentheses.

Let's execute.

[Assistant] I'll run a final, more efficient SPARQL query that selects items which are either instances (P31) of video game genre (Q659563), or direct subclasses (P279) of video game genre or electronic game, returning the item, its English label, its OLAC ID (P6352) if present, and any direct subclasses (with labels). I'll execute that query now.

[Assistant] The endpoint finally returned results for a simplified query, listing many items including non-genre items. Given the user's request, I'll provide the final SPARQL query that returns distinct items meeting the criteria, with their OLAC ID and any direct subclasses. I'll explain my steps and present the query. I'll include rdfs:label optional to get English labels. I'll ensure the query returns IRIs (item identifiers) as required. Now I'll finalize by sending the SPARQL query and a brief summary of what it returns.
